[0032] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0033] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] refer to Figure 1-2 In one embodiment, the power supply device 100 includes a housing 10 and a battery module 20 (see...). Figure 6 The battery module 20 is disposed within the housing 10. The current output module 30 includes a wire 31 and a current output interface 32. One end of the wire 31 is electrically connected to the battery module 20, and the other end of the wire 31 extends from the inside of the housing 10 and connects to the current output interface 32. The outer surface of the housing 10 is provided with a guide 11 and an interface positioning part 12. The guide 11 provides guidance for the wire 31, and the interface positioning part 12 cooperates with the current output interface 32 to detachably connect the current output interface 32 to the housing 10. In this embodiment, the power supply device 100 is an automotive emergency jump starter. It is understood that the above technical solution is applicable to power supply devices with cable management, guidance, fixing, or protection requirements, and is not limited to automotive emergency jump starters; it is also applicable to other types of power supply devices.

[0035] With the above-described structure, the wire 31 extending from the outer surface of the housing 10 can be guided by the guide member 11, and the current output interface 32 can be detachably connected to the housing 10 by cooperating with the interface positioning part 12. This allows for the organization and guidance of the wire 31, and the wire 31 can be fixed by the cooperation of the current output interface 32 and the interface positioning part 12. As a result, the wire 31 can be close to or adhere to the outer surface of the housing 10, which helps to maintain the overall compactness of the power supply device 100 and minimize the storage space required by the power supply device 100. In addition, it can also prevent the wire 31 from being damaged or having poor contact due to bending, pulling, squeezing, etc.

[0036] refer to Figure 6In one embodiment, the outer casing 10 is generally cubic in shape and includes a first side plate 101, a second side plate 102, a top plate 103, and a bottom shell 104. The bottom shell 104 includes a bottom plate 1041, a front plate 1042 protruding from the front end of the bottom plate 1041, and a rear plate 1043 protruding from the rear end of the bottom plate 1041. The bottom ends of the first side plate 101 and the second side plate 102 are respectively fixed (e.g., by screws) to opposite sides of the bottom plate 1041. The top plate 103 is connected to the top ends of the first side plate 101, the second side plate 102, the front plate 1042, and the rear plate 1043. The first side plate 101, the second side plate 102, the top plate 103, and the bottom shell 104 together form a space for accommodating the battery module 20 and other components. Understandably, the construction of the housing 10 is not limited to the aforementioned situation, and other suitable constructions may be adopted in other embodiments, as long as they can provide housing space for the battery module 20 and other components.

[0037] In this embodiment, the power supply device 100 is a car emergency jump starter, therefore, as Figure 4 and Figure 5 As shown, there are two current output modules 30, which are used for electrical connection to the positive and negative terminals of the car battery, respectively. That is, the wires 31 of the two current output modules 30 are electrically connected to the positive and negative terminals of the car battery, respectively. Therefore, the two wires 31 are also referred to as the positive connection wire and the negative connection wire, respectively. In this embodiment, the outer surface of the aforementioned housing 10 refers to the outer surface 1011 of the first side plate 101 (see...). Figure 6 The outer side 1021 of the second side plate 102, the outer side 1011 and the outer side 1021 are both provided with guide members 11 and interface positioning parts 12.

[0038] In one embodiment, the two wires 31 extend from one end (i.e., end A, see) along the length of the housing 10. Figure 5 ) out, as Figure 4 As shown, the first portion 311 of each wire 31 exposed outside the housing 10 initially extends along the height direction Y of the housing 10 until its extension direction is changed by the guide member 11. Thereafter, the second portion 312 of the wire 31 exposed outside the housing 10, connected to the first portion 311, extends along the length direction X of the housing 10. The third portion 313 of the wire 31 exposed outside the housing 10, connected to the second portion 312 and the current output interface 32, is generally arc-shaped so that the current output interface 32 faces the interface positioning portion 12. In this embodiment, to meet the requirement of the wire 31 being as long as possible, the guide member 11 is provided near a corner close to the first side plate 101 / second side plate 102.

[0039] refer to Figure 1 , Figure 4 and Figure 6In one embodiment, the guide 11 includes a body 111 protruding from the outer surface of the housing 10. The body 111 includes a first side 1111 and a second side 1112 extending in different directions. The conductor 31 is guided by the first side 1111 and the second side 1112. In this embodiment, the body 111 is generally a protrusion. The first side 1111 and the second side 1112 are generally perpendicular to the surface on which the body 111 protrudes. The first side 1111 extends generally along the height direction of the housing 10, and the first side 1112 extends generally along the length direction of the housing 10. A first portion 311 of the conductor 31 is attached to the first side 1111 and guided by the first side 1111, extending generally along the height direction of the housing 10. A second portion 312 of the conductor 31 is attached to the second side 1112 and guided by the first side 1111, extending generally along the length direction of the housing 10. With the above-described structure, the guide 11 can provide guidance for the wire 31 and change the extension direction of the wire 31.

[0040] In one embodiment, the guide 11 further includes a limiting wall 1113 projecting from a first side 1111 and a second side 1112 of the body 111 (see...). Figure 4 The limiting wall 1113 and the outer surface of the housing 10 cooperate to prevent the wire 31 from detaching from the main body 111. In this embodiment, the limiting wall 1113 faces the surface protruding from the main body 111, and the limiting wall 1113, the outer surface of the housing 10, and the first side surface 1111 and the second side surface 1112 form an L-shaped guide groove 1114 (see...). Figure 1 The first portion 311 of the wire 31 is partially engaged in the guide groove 1114, and the second portion 312 of the wire 31 is also partially engaged in the guide groove 1114. The wire 31 is restricted by the limiting wall 1113 and the outer surface of the housing 10 and cannot detach from the main body 111. With this configuration, the guide member 11 not only provides guidance for the wire 31 but also provides fixation for the wire 31 in the width direction Z of the housing 10, that is, the wire 31 cannot move in the width direction Z of the housing 10. Since the current output interface 32 can be detachably connected to the housing 10 by cooperating with the interface positioning part 12, and the guide member 11 can provide fixation for the wire 31 in the width direction Z of the housing 10, this configuration is beneficial because the entire wire 31 is approximately in the same plane and approximately in contact with the outer surface of the housing 10, thereby contributing to the overall compactness of the power supply device 100.

[0041] Understandably, the construction of the guide 11 is not limited to the foregoing. In another embodiment, the guide 11 may consist only of a first side 1111 extending along the height direction of the housing 10, in which case the limiting wall 1113 protrudes from the first side 1111. In yet another embodiment, the guide 11 may consist only of a second side 1112 extending along the length direction of the housing 10, in which case the limiting wall 1113 protrudes from the second side 1112. In yet another embodiment, the guide 11 includes two guide walls protruding from the outer surface of the housing 10, and the wire 31 passes through the interior of the housing 10 and changes its extension direction by passing through a guide groove formed between the two guide walls. For example, the two guide walls are spaced apart from each other and both extend along the height direction of the housing 10, thereby forming a straight guide groove extending along the height direction of the housing 10. The first portion 311 of the wire 31 extends into the straight guide groove from the bottom end and exits from the top end of the straight guide groove. The extension direction of the wire 31 changes from the top of the straight guide groove, so that the second part 312 of the wire 31 extends along the length direction of the housing 10.

[0042] Understandably, in some cases, the wire 31 may pass through the vicinity of the guide 11, in which case the guide 11 may only have a second side 1112 to provide guidance for the wire 31 in the length direction of the housing 10. That is, after the wire 31 passes through the housing 10, it no longer needs to extend along the height direction of the housing 10 and then along the length direction of the housing 10, but can extend directly along the length direction of the housing 10.

[0043] In another embodiment, the guide 11 includes a plurality of hooks protruding from the outer surface of the housing 10, into which different portions of the wire 31 engage. The plurality of hooks includes hooks arranged along the height direction of the housing 10 and hooks arranged along the length direction of the housing 10. With this configuration, the guide 11 can also achieve... Figure 1 The routing method of wire 31 in the diagram.

[0044] Understandably, such as Figure 1 The number of guide members 11 shown is not limited to one. For example, the number of guide members 11 can be two, in which case, besides Figure 1In addition to the first guide member 11 located at the upper right corner near the first side panel 101, as shown in the diagram, the power supply device 100 also includes a second guide member 11 located at the upper left corner near the first side panel 101. In this embodiment, the wire 31 undergoes a first change in extension direction at the first guide member 11 located at the upper right corner near the first side panel 101, that is, it changes from extending along the height direction of the housing 10 to extending along the length direction of the housing 10. The wire 31 undergoes a second change in extension direction at the second guide member 11 located at the upper left corner near the first side panel 101, that is, it changes from extending along the length direction of the housing 10 to extending along the height direction of the housing 10. In yet another embodiment, the number of guide members 11 can be three, that is, in addition to the two first guide members 11 in the aforementioned embodiments, the power supply device 100 also includes a third guide member 11 located at the lower left corner near the first side panel 101. In this embodiment, the wire 31 undergoes a first change in extension direction at the first guide member 11 located at the upper right corner near the first side panel 101, that is, it changes from extending along the height direction of the housing 10 to extending along the length direction of the housing 10. The wire 31 undergoes a second change of extension direction at the second guide 11 located near the upper left corner of the first side plate 101, that is, it changes from extending along the length direction of the housing 10 to extending along the height direction of the housing 10. The wire 31 undergoes a third change of extension direction at the third guide 11 located near the lower left corner of the first side plate 101, that is, it changes from extending along the height direction of the housing 10 to extending along the length direction of the housing 10.

[0045] In one embodiment, the current output interface 32 is a starter clip, and the interface positioning part 12 is a positioning block protruding from the outer surface of the housing 10, on which the starter clip is clamped. The starter clip is conventional and known, comprising two jaws 321 rotatably connected to each other and a torsion spring 322 located between the two jaws 321 (see...). Figure 1 The torsion spring 322 applies a pushing force to the two grippers 321, causing them to clamp tightly onto the positioning block. In this embodiment, the positioning block is made of plastic material; in other embodiments, it can also be made of an elastic material, such as rubber. When the actuating clamp is clamped onto the positioning block, the positioning block undergoes elastic deformation, ensuring sufficient contact between the grippers 321 and the positioning block. This increases the friction between the grippers 321 and the positioning block, preventing the grippers 321 from easily loosening.

[0046] In one implementation, reference Figure 3 and Figure 6The positioning block has grooves 123 on its two opposite sides (top surface 121 and bottom surface 122), and the two grippers 321 of the starting clamp are partially received in these two grooves 123. The width of the groove 123 is slightly larger than the width of the grippers 321. When the user clamps the grippers 321 onto the positioning block, the front end of the grippers 321 can abut against one end of the groove 123 in its length direction. At this time, the grippers 321 are restricted by the groove 123 at one end in its length direction and both ends in its width direction, further restricting the grippers 321 so that they do not easily detach from the positioning block.

[0047] Understandably, the structure of the interface positioning part 12 is not limited to the aforementioned. For example, in another embodiment, the interface positioning part 12 is a magnet disposed inside the housing 10, and a magnet or iron block is fixed to the position of the starting clip facing the interface positioning part 12. The starting clip is detachably connected to the housing 10 by the magnetic attraction force of the magnet. In yet another embodiment, the interface positioning part 12 is a positioning block protruding from the outer surface of the housing 10. One side of the positioning block is provided with a receiving hole for receiving the starting clip, and the front end of the starting clip is received in the receiving hole, thereby detachably connecting the starting clip to the housing 10.

[0048] refer to Figure 1 and Figure 3 In one embodiment, the outer surface of the housing 10 is provided with a recess 13, in which both the guide 11 and the interface positioning portion 12 are received. In this embodiment, both the guide 11 and the interface positioning portion 12 protrude from the bottom surface 131 of the recess 13. The recess 13 can be configured to have sufficient depth so that the wire 31 and the current output interface 32 can be completely received in the recess 13 without protruding from the annular surface 14 surrounding the recess 13 of the housing 10. This arrangement can, to some extent, prevent the user or other objects from accidentally touching the wire 31 and / or the current output interface 32, causing the wire 31 to detach from the guide 11 or the current output interface 32 to detach from the interface positioning portion 12.

[0049] refer to Figure 1 , Figure 4 and Figure 6 In one embodiment, the housing 10 of the automotive starter power supply 100 is provided with an air inlet (described in detail later) and a through hole 15 (specifically located on the front panel 1042 of the bottom housing 104). The automotive starter power supply 100 also includes a fan 40 (see...). Figure 7 The fan 40 is disposed inside the housing 10. The end cap 50 is connected to the housing 10 and covers the through hole 15. The end cap 50 is provided with an air outlet 51 communicating with the through hole 15. The fan 40 drives airflow through the battery module 20 and towards the air outlet 51.

[0050] With this structure, outside air can enter the housing 10 through the air inlet. After the fan 40 starts working, it drives the air to flow and form an airflow through the battery module 20. During this process, the heat generated by the battery module 20 flows with the airflow to the air outlet 51 and is finally discharged to the outside of the housing 10, which is conducive to the dissipation of heat inside the housing 10.

[0051] Understandably, there are many suitable locations for the air inlet on the housing 10. In this embodiment, a concealed air inlet is adopted in order not to negatively affect the appearance of the power supply device 100. Specifically, the air inlet is a plurality of through holes 133 provided on the side 132 surrounding the bottom surface 131 of the recess 13 of the housing 10 (see...). Figure 3 The through-hole 133 extends from the side 132 to the inner surface of the housing 10. After the fan 40 starts operating, outside air can continuously flow into the interior of the housing 10 through the through-hole 133. Since the through-hole 133 is only visible to the user at limited specific angles, it is not visible to the user in most scenarios, thus not negatively impacting the aesthetic appearance of the power supply unit 100. Understandably, the construction of the air inlet is not limited to the aforementioned situation. For example, in another embodiment, the air inlet is an elongated slot provided on the side 132 surrounding the bottom surface 131 of the recess 13 of the housing 10.

[0052] refer to Figure 6 , Figure 7 and Figure 8 In one embodiment, the power supply device 100 further includes an inflation mechanism assembly 60, which includes a motor 61, an air compressor 62 connected to the motor 61, and an air pipe 63 connected to the air compressor 62. The motor 61 and the air compressor 62 are both disposed inside the housing 10. One end of the air pipe 63 extends out from the inside of the housing 10 and is wound around the end cap 50, so the end cap 50 is also referred to as the winding portion 50.

[0053] With the above-described structure, the power supply device 100 can also function as an electric air pump. The motor 61 drives the air compressor 62 to output compressed air, enabling the power supply device 100 to inflate items such as car tires, bicycle tires, sports balls, and air mattresses.

[0054] In one embodiment, the motor 61 is a rotary motor extending along a first direction (i.e., the length direction X of the housing 10), and the air compressor 62 extends along a second direction intersecting the first direction; for example, the air compressor 62 may extend along the height direction Y of the housing 10. In this case, the first and second directions are substantially perpendicular. It is understood that in other embodiments, the first and second directions may be chosen to be non-perpendicular to each other, depending on actual needs. The battery module 20 is partially housed within the space defined by the motor 61 and the air compressor 62.

[0055] In one embodiment, the air compressor 62 is a piston-type air compressor, comprising a cylinder, a connecting rod, and a piston. One end of the connecting rod is connected to the motor shaft of the motor 61, and the other end of the connecting rod 61 is connected to the piston located in the cylinder. Rotation of the motor shaft of the motor 61 drives the connecting rod to swing, which in turn drives the piston to move repeatedly within the cylinder, thereby compressing the air in the cylinder. The compressed air is ultimately output to the object to be inflated through the air pipe 63. Understandably, piston-type air compressors are known, and their specific construction has been described in published materials and will not be repeated here. In another embodiment, the air compressor 62 can be of other types, such as a diaphragm-type air compressor.

[0056] In one embodiment, the power supply device 100 further includes a transmission device 64, the input end of which is connected to the motor shaft of the motor 61, and the output end of which is connected to the air compressor device 62. The transmission device 64 transmits the rotational motion from the motor 61 to the air compressor device 62.

[0057] In one embodiment, the power supply device 100 further includes a heat sink 65 (see...). Figure 9 The heat sink 65 is connected to the air compressor 62. For example, the heat sink 65 can be fixed to one end of the cylinder of the air compressor 62. The heat sink 65 can be made of a material with good heat dissipation properties, such as aluminum alloy. Figure 9 As shown, in one embodiment, the heat sink 65 can be fixed to the transmission device 64 by fasteners (e.g., bolts).

[0058] The motor 61, air compressor 62, and transmission device 64, which are connected together, generally form an L-shaped structure. Figure 7 From the displayed perspective, the battery module 20 is partially housed within the space defined by the motor 61 and the air compressor 62, meaning that a portion of the battery module 20 is located above the motor 61 and to the left of the air compressor 62. This fully utilizes the space defined by the motor 61 and the air compressor 62, contributing to a compact overall structure.

[0059] In one embodiment, the heat sink 65 is aligned with the through hole 15 of the housing 10. Thus, a portion of the heat generated by the air compressor 62 during operation, which is transferred to the heat sink 65, can easily flow through the through hole 15 to the outside of the housing 10 along with the airflow passing through the heat sink 65. In this embodiment, the fan 40 is disposed between the heat sink 65 and the through hole 15. Thus, when the fan 40 operates, the suction it generates draws air outward from the housing 10, causing the air inside the housing 10 to flow outward. Outside air can continuously flow into the interior of the housing 10 through the through hole 133. The flowing airflow passes through the battery module 20 and the motor 61, then through the air compressor 62 and the heat sink 65. Finally, the flowing airflow, carrying the heat generated by the battery module 20, the motor 61, and the air compressor 62, is discharged from the air outlet 51.

[0060] refer to Figure 7 , Figure 11 and Figure 12 In one embodiment, the power supply device 100 further includes an inner housing 70 (see...). Figure 6 The motor 61, air compressor 62, transmission device 64, and heat sink 65 are located between the bottom of the inner shell 70 and the outer shell 10. Specifically, the inner shell 70 includes a chamber portion 71 and a partition 72. The chamber portion 71 has an open end and includes a top plate 711, two side plates 712, and a back plate 713. The two side plates 712 protrude from the top plate 711 and are spaced apart from each other by a certain distance. The back plate 713 protrudes from the top plate 711 and is located between the two side plates 712. The ends of the two side plates 712 and the back plate 713 opposite to the top plate 711 form the open end of the chamber portion 71. Through this open end, the air compressor 62 can be placed into the space defined by the top plate 711, the two side plates 712, and the back plate 713.

[0061] In one embodiment, the fan 40 is housed within the chamber 71 and located at the opening between the two side plates 712, opposite the back plate 713. The back plate 713 is provided with a through hole 7131, so that when the fan 40 is working, the suction force it generates draws air outward from the housing 10, causing the air inside the housing 10 to flow outward. The flowing airflow passes through the battery module 20 and the motor 61, and then enters the interior of the chamber 71 through the through hole 7131. After passing through the air compressor 62 and the heat sink 65, the flowing airflow finally carries the heat generated by the battery module 20, the motor 61, and the air compressor 62 and is discharged from the air outlet 51. Understandably, the installation position of the fan 40 is not limited to the aforementioned. For example, it can be installed near the end A of the housing 10. In this case, when the fan 40 is working, the thrust it generates pushes the air inside the housing 10 outward, causing the air inside the housing 10 to flow outward. The flowing airflow passes through the battery module 20, the motor 61, the air compressor 62, and the heat sink 65. The flowing airflow eventually carries the heat generated by the battery module 20, the motor 61, and the air compressor 62 and is discharged from the air outlet 51.

[0062] The partition 72 is connected to the end of the back plate 713 opposite to the top plate 711. Figure 6 From the displayed perspective, the battery module 20 is located above the separator 72, while the motor 61 is located below the separator 72. In one embodiment, two support portions 721 are provided on the surface of the separator 72 opposite to the motor 61 (see...). Figure 12 The bottom plate 1041 of the bottom shell 104 of the outer casing 10 has two support portions 1044 on the surface opposite to the motor 61 (see...). Figure 13 The two support parts 721 and the two support parts 1044 are in contact with the circumferential side of the motor 61, so that the motor 61 is clamped between the partition 72 and the base plate 1041.

[0063] In one implementation, such as Figure 7 As shown, the battery module 20 includes a battery casing 21 and a battery cell 22. The positive and negative connection lines (i.e., the two aforementioned wires 31) are respectively connected to the positive and negative terminals of the battery cell 22. The battery cell 22 is located between the battery casing 21 and the inner casing 70, and the battery casing 21 is fixed to the inner casing 70. Figure 11 From the displayed perspective, a groove 722 is provided on the top of the separator 72. The battery cell 22 is partially housed in the groove 722. The battery casing 21 is generally cubic with one open end, and its open end faces the top of the separator 72 of the inner casing 70, allowing it to be fitted onto the battery cell 22. After the battery casing 21 is fixed to the separator 72, the battery cell 22 is fixed within the space formed by the battery casing 21 and the separator 72.

[0064] refer to Figure 4and Figure 5 In one embodiment, the end cap 50 includes a body 52 and a limiting wall 53 protruding from the side 521 of the body 52. ​​The air tube 63 is wrapped around the side 521 of the body 52 and is confined between the limiting wall 53 and the housing 10. In one embodiment, a slot 531 is provided on the end face 532 of the limiting wall 53 facing away from the body 52. ​​The air tube 63 is inserted into the slot 531 and connected to the limiting wall 53. With this structure, when not in use, the user can wrap the air tube 63 around the side 521 of the body 52 and insert its end portion into the slot 531. This provides organization, guidance, fixation, or protection for the air tube 63 and helps maintain the overall compactness of the power supply device 100, minimizing the storage space required by the power supply device 100. In addition, it can prevent damage or poor contact of the air tube 63 due to bending, pulling, squeezing, etc.

[0065] In one embodiment, the body 52 further includes a receiving cavity 54 extending from the end face 532 of the limiting wall 53 toward the outer casing 10, and the air outlet 51 includes a plurality of through holes 541 disposed on the bottom surface of the receiving cavity 54 of the body 52. ​​In this embodiment, the bottom surface of the receiving cavity 54 is also provided with a locking portion 542, which has a slot for accommodating one or more air nozzle clamps 64. When needed, the user can install a suitable air nozzle clamp 64 onto the end of the air tube 63 so that the air tube 63 can be detachably connected to an object to be inflated with a corresponding air nozzle.

[0066] refer to Figure 6 , Figure 7 and Figure 8 In one embodiment, the power supply device 100 further includes a main control circuit board 80, which is located inside the housing 10. Figure 6 From the displayed perspective, the main control circuit board 80 is located above the battery module 20 and the inner casing 70, and is fixed to the top plate 103 of the casing 10. The main control circuit board 80 includes electronic components for implementing various functions of the power supply device 100. For example, in one embodiment, a switch 81 (see...) is provided on the main control circuit board 80. Figure 14 and Figure 15The switch 81 can be used to switch the circuit on and off, or to send commands to the control chip (not shown) on the main control circuit board 80. For example, the switch 81 can be a rotary potentiometer, comprising a body 811 and a rotating rod 812 rotatably connected to the body 811. Rotation of the rotating rod 812 relative to the body 811 causes a change in resistance within the body 811. The control chip on the main control circuit board 80 performs corresponding operations based on the change in resistance. For example, the control chip on the main control circuit board 80 can decrease the compressed air pressure output by the air compressor 62 based on a decrease in resistance, and increase the compressed air pressure output by the air compressor 62 based on an increase in resistance.

[0067] The power supply device 100 also includes a control button 82 for triggering the switch 81. In this embodiment, the housing 10 is provided with a through hole, specifically a through hole 1031 provided on the top plate 103 (see...). Figure 6 The control button 82 is movably housed in the through hole 1031, and the switch 81 is located below the control button 82. The power supply device 100 also includes a waterproof structure 83 located below the control button 82, which prevents liquid flowing through the gap between the control button 82 and the through hole 1031 from entering the interior of the housing 10.

[0068] Because of the waterproof structure 83, the power supply unit 100 will not be affected or damaged when it operates in certain harsh environments due to liquid from the external environment entering the interior of the housing 10 through the gap between the control button 82 and the through hole 1031.

[0069] refer to Figure 14 and Figure 15In one embodiment, the waterproof structure 83 includes a partition 84, a sealing element support 85, and a sealing element 86. The partition 84 is located below the control button 82 and covers the through hole 1031 of the housing 10. The partition 84 has a through hole 841 through which the sealing element support 85 passes. The surface of the body 842 (mentioned below) facing the control button 82 may also be formed with a step surrounding the through hole 841. This step can prevent a small amount of moisture entering the surface of the body 842 facing the control button 82 from the gap between the control button 82 and the partition 84 from directly penetrating downwards along the through hole 841 to the main control circuit board 80. In this embodiment, the sealing element support 85 is fixedly connected to the control button 82 and can rotate and move up and down synchronously with the control button 82. The sealing element support 85 can be fixedly connected to the control button 82 by one or more of the following methods: tight fit, adhesive, snap-fit, etc. In other embodiments, the sealing element carrier 85 may not be fixedly connected to the control button 82, meaning that the sealing element carrier 85 and the control button 82 cannot perform one or both of the functions of synchronous rotation and up-down movement. The seal 86 is connected to the sealing element carrier 85 and seals the gap between the sealing element carrier 85 and the through hole 841 of the partition 84.

[0070] In one embodiment, the sealing element support portion 85 is a hollow cylinder, and one end of the sealing element support portion 85 is connected to the control button 82. Specifically, the sealing element support portion 85 includes a receiving cavity 851, which has a first open end 852 and a second open end 853. The switch 81 extends into the receiving cavity 851 from the first open end 852. The control button 82 is provided with a receiving hole 821 with one open end. A connecting post 822 protrudes from the bottom surface of the receiving hole 821. The sealing element support portion 85 is partially received in the receiving hole 821 of the control button 82. The connecting post 822 extends into the receiving cavity 851 from the second open end 853 and is connected to the switch 81.

[0071] When the switch 81 can be a rotary potentiometer, the control button 82 is a knob. The user can rotate the control button to make it rotate relative to the housing 10. The rotation of the control button 82 then drives the rotating rod 812 of the switch 81 to rotate. In this embodiment, the control button 82 is a rotating body, which includes a circular base 823 and a sidewall 824 surrounding the base 823. A cylinder 825 protrudes from the inner surface of the base 823, and the cylinder 825 defines a receiving hole 821 with one end open. The bottom surface of the receiving hole 821 with the aforementioned protruding connecting post 822 is also the inner surface of the base 823.

[0072] In one embodiment, the connecting post 822 is provided with a receiving hole 8221, and the rotating rod 812 is partially and fixedly received in the receiving hole 8221. For example, one or more methods such as tight fitting, adhesive, or snap-fit ​​are used to achieve a fixed connection between the rotating rod 812 and the control button 82, preventing the control button 82 from easily loosening and falling off. The rotating rod 812 has a non-circular cross-section, and the receiving hole 8221 of the connecting post 822 has a shape that matches the rotating rod 812. Thus, when the rotating rod 812 is partially received in the receiving hole 8221, the rotating rod 812 can rotate coaxially with the connecting post 822. That is, the rotating rod 812 of the switch 81 can rotate coaxially with the control button 82.

[0073] In one embodiment, the seal 86 is an elastic sealing ring, and a groove 854 is provided on the circumferential side of the seal support portion 85. The seal 86 is fitted onto the circumferential side of the seal support portion 85 and partially received in the groove 854. With this structure, the seal 86 is securely fixed to the seal support portion 85.

[0074] In one embodiment, the power supply device 100 further includes an elastic element 87 (e.g., a cylindrical helical spring) disposed between the control button 82 and the partition 84. The two ends of the elastic element 87 abut against the control button 82 and the partition 84 respectively, and the elastic element 87 is in a compressed state. The elastic element 87 applies a pushing force to the control button 82 and the partition 84, thereby causing the seal 86 to tightly seal the gap between the seal support portion 85 and the through hole 841 of the partition 84, thereby ensuring good waterproof performance.

[0075] refer to Figure 16 In one embodiment, the inner surface of the outer casing 10 (i.e., the inner surface of the top plate 103) protrudes with a fixing wall 1032 surrounding the through hole 1031 of the outer casing 10. The fixing wall 1032 is provided with a plurality of engaging holes 1033. The partition 84 includes a body 842 (see...) Figure 14 ) and multiple hooks 843 protruding from one end of the body 842 (see Figure 14 The plurality of hooks 843 respectively engage with the plurality of engagement holes 1033, thereby connecting the partition 84 to the housing 10. It is understood that in other embodiments, the partition 84 may employ other suitable and disclosed connection means, for example, it may be fixed to the housing 10 by fasteners (e.g., screws).

[0076] refer to Figures 7 to 10In one embodiment, the power supply device 100 further includes a positive electrode connector 23 electrically connected to the positive electrode of the battery cell 22, a negative electrode connector 24 electrically connected to the negative electrode of the battery cell 22, and a circuit board 90. The positive electrode connection wire is electrically connected to the positive electrode connector 23 via the circuit board 90, or the negative electrode connection wire is electrically connected to the negative electrode connector 24 via the circuit board 90. In one embodiment, the circuit board 90 is provided with a positioning groove 91 (see...). Figure 17 One of the positive electrode connector 23 and the negative electrode connector 24 is provided with a positioning part 25 (see...). Figure 8 The positioning part 25 is inserted into the positioning groove 91, thereby achieving the positioning of one of the positive electrode connector 23 and the negative electrode connector 24 relative to the circuit board 90 and their electrical connection with the circuit board 90. For example, Figure 10 The positive terminal connection wire is electrically connected to the positive terminal connector 23 via the circuit board 90.

[0077] In one embodiment, the positive electrode connector 23 and the negative electrode connector 24 are fixed to one end of the battery casing 21 along its length. In another embodiment, both the positive electrode connector 23 and the negative electrode connector 24 include a body 26 and a bent portion 27 connected to the body 26. The body 26 and the bent portion 27 intersect each other, with one end of the body 26 connected to one end of the bent portion 27. The body 26 of one of the positive electrode connectors 23 and 24, which is electrically connected to the circuit board 90, is fixed to one end of the battery casing 21 along its length, while its bent portion 27 extends in a direction parallel to the length of the battery casing 21. The positioning portion 25 protrudes from the bent portion 27 and extends along the length of the bent portion 27. Thus, after the positioning portion 25 is inserted into the positioning groove 91 of the circuit board 90, the circuit board 90 is approximately parallel to the side of the battery casing 21 facing the bent portion 27.

[0078] In one implementation, such as Figure 17 As shown, the positioning groove 91 is a straight groove extending along a straight line, and the positioning part 25 is a strip-shaped protrusion provided corresponding to the positioning groove 91. Thus, after the positioning part 25 is inserted into the positioning groove 91, the circuit board 90 cannot move relative to either the positive electrode connector 23 or the negative electrode connector 24 connected thereto. It is understood that the construction of the positioning groove 91 and the positioning part 25 is not limited to the aforementioned situation. For example, in another embodiment, there are multiple positioning parts 25 and positioning grooves 91; for example, each positioning part 25 is a square protrusion, and each positioning groove 91 is a square through hole. These multiple positioning parts 25 are arranged along the length direction of the bent portion 27 and are respectively inserted into the multiple positioning grooves 91.

[0079] Regardless of the construction of the positioning groove 91, the circuit board 90 also includes a pad 92 surrounding the positioning groove 91. Thus, after the positioning part 25 is inserted into the positioning groove 91, the positioning part 25 can be soldered to the pad 92.

[0080] In one embodiment, the bodies 26 of the positive electrode connector 23 and the negative electrode connector 24 are both connected to the same end fixed to the battery casing 21 along its length. The bent portions 27 of the positive electrode connector 23 and the negative electrode connector 24 face two opposite sides of the battery casing 21, respectively. One of the positive electrode connectors 23 and 24 can be directly electrically connected to the positive or negative electrode connection line without requiring a circuit board 90. For example, Figure 10 The image shows that the negative electrode connector 24 is directly electrically connected to the negative electrode connecting wire. In this case, the bent portion 27 of the negative electrode connector 24 and the circuit board 90 are located on opposite sides of the battery casing 21. In this embodiment, a wire fixing portion 28 is connected to the end of the bent portion 27 of the negative electrode connector 24. One end of the negative electrode connecting wire can be fixed to the wire fixing portion 28 by welding or riveting.

[0081] In one embodiment, the power supply device 100 further includes a fixing member 93, and the circuit board 90 is further provided with a fixing groove 94 (see...). Figure 17 The fixing groove 94 is electrically connected to the positioning groove 91. For example, the circuit board 90 also includes pads 95 surrounding the fixing groove 94 (see...). Figure 17 Pad 95 is electrically connected to pad 92, thus achieving an electrical connection between the fixing groove 94 and the positioning groove 91. The fixing member 93 includes a main body 931 and a wire fixing part 932 connected to the main body 931. The main body 931 is inserted into the fixing groove 94 and can be soldered to pad 95. The positive or negative connection wire is fixed to the wire fixing part 932. For example, Figure 10 The diagram shows that one end of the positive electrode connecting wire is fixed to the wire fixing part 932. With this structure, the positive electrode connecting wire is electrically connected to the positive electrode connector 23 via the fixing groove 94 and the positioning groove 91 on the circuit board 90. In one embodiment, one end of the positive electrode connecting wire can be fixed to the wire fixing part 932 by welding or riveting. In one embodiment, the fixing groove 94 and the positioning groove 91 are parallel or perpendicular. Of course, the positional relationship between the fixing groove 94 and the positioning groove 91 is not limited to this; other suitable arrangements can be adopted according to actual needs.

[0082] In one embodiment, the power supply device 100 further includes a relay 96 disposed on the circuit board 90 (see...). Figure 7The fixing slot 94 and the positioning slot 91 are both connected to the relay 96, which controls the on / off state of the circuit between the fixing slot 94 and the positioning slot 91. Thus, when the power supply device 100 is used as an emergency jump starter for a car, if the two current output ports 32 (i.e., the starter clips) are correctly connected to the positive and negative terminals of the car battery, the relay 96 is controlled to switch the circuit between the fixing slot 94 and the positioning slot 91 from an open state to an on state. This allows the positive connection wire to establish an electrical connection with the positive connector 23. Afterward, the power supply device 100 can output the required current to the car battery. If it is detected that the two current output ports 32 (i.e., the starter clips) are not correctly connected to the positive and negative terminals of the car battery—for example, the current output port 32 connected to the positive connection wire is connected to the negative terminal of the car battery—the relay 96 will not be controlled to switch the circuit between the fixing slot 94 and the positioning slot 91 from an open state to an on state. This prevents damage caused by the user incorrectly connecting the two current output interfaces 32 to the positive and negative terminals of the car battery.

[0083] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this utility model.
